The NASA Landsat Data Collection (NLDC) contains multispectral scanner (MSS) and thematic mapper (TM) data purchased by NASA investigators. These data have been acquired from Space IMAGING EOSAT, the National Satellite Land Remote Sensing Data Archive (NSLRSDA) at the National Center for Earth Resources Observation & Science (EROS), and from International Ground Stations. These data have been processed to Level-1 (systematic geometric and radiometric corrections), and the processing parameters (projection, resampling method, pixel and cell size) vary depending on what the investigator specified at the time of the data purchase. Customers that are qualified as USGAU need only complete and file this form once. There are also some scenes that were acquired for the Humid Tropical Forest Project (HTFP) that can be acquired in their original format or geographically referenced to a UTM projection (using satellite ephemeris data only) with embedded tic-marks annotated with UTM coordinates.

To search geographic coverage of NLDC data, use EarthExplorer. The search can be constrained by specifying additional geographic and temporal parameters.
NOTE: The NLDC data are provided in a "user beware" context which implies that the USGS Customer Services do not have documentation describing International Ground Stations data formats.
